5.21 Btu / GSF / Degree-Day (°F)

Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	6,886,089 Kilowatt-hours	23,495.34 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	11,710,121 Kilowatt-hours	39,954.93 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	2,290.65 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

65,740.92 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

1,745,159 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	July 1, 2019	June 30, 2020

A brief description of when and why the energy consumption baseline was adopted:

FY20 is the year we had data available for

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.04 MMBtu per square foot	0.07 MMBtu per square foot
Baseline year	0.04 MMBtu per square foot	0.06 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

Trinity’s full time sustainability coordinator, the sustainability committee, and the facilities operations team work to incorporate energy efficiency into all projects and daily operations. Sustainability Coordinator and student Eco-Reps educate the campus community on individual energy efficiency efforts they can practice each day.

A brief description of energy use standards and controls employed by the institution:

In 2018 Trinity began developing a campus wide “Energy Policy” to establish heating and cooling temperature set-point standards, occupancy schedules, and set back temperatures. Energy efficiency sequences of operation are incorporated into all HVAC upgrades and new construction.

The new heating and cooling equipment in the new 2,500 SF mechanical room space at B&G Building will be connected into the existing campus-wide Building Management System that is operated and maintained by ABM.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

All new buildings or renovations will be all LED. LED conversions will be looked at on a building by building basis for other spaces based on savings/payback.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Trinty has 4 solar arrays on campus which harvest sunlight to create electricity which is fed back into the power grid.

A brief description of co-generation employed by the institution:

1.4 MW Fuel Cell with Steam waste heat recovery tied into south campus main substation and central energy plant.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Trinity requires design consultants to follow the 2021 edition of the International Energy Conservation Code (IECC) for new projects.
